The television show Pretty Betty has been successful for many years. That show recently had a share of 20, which means, that among the TV sets in use, 20% were tuned to Pretty Betty. An advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 12 households have TV sets in use at the time of a Pretty Betty broadcast. Find the probability that none of the households are tuned to Pretty Betty. P(none) = Find the probability that at least one household is tuned to Pretty Betty. P(at least one) = Find the probability that at most one household is tuned to Pretty Betty. P(at most one) D If at most one household is tuned to Pretty Betty, does it appear that the 20% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Pretty Betty unusual?) O no, it is not wrong Oyes, it is wrong Question Help: Message instructor DPost to forum
